Synopsis A cold front will continue to push southeast out of
the area this evening as showers gradually decrease in coverage
and intensity. The area will be between storm systems on Tuesday,
with another front tracking through on Wednesday, followed by
continued showery weather on Thursday.

Discussion The main band of frontal precipitation has shifted
e of the county warning area. Snow levels fell to around 3000 feet
in some areas, with light snow amounts. Precipitation behind the
frontal band is more convective in nature as instability increases
across the area. This activity is mainly occurring near and N of
cape mendocino, both over land and the adjacent coastal waters.

Showers over the coastal waters has been the heaviest, with cloud
tops periodically cooling, especially near and just N of cape
mendocino. Showers are oriented nearly parallel to the redwood
coast, but the lines have been gradually shifting E toward the
coast. For the remainder of the afternoon and early evening hours,
this will be the most likely location for isolated thunderstorm
development. After 00z, have included isolated thunder over the
coastal waters and along the coast generally near and N of
patrick's point. It is in this area the the best chances of sub-
zero lifted indices and capes around 500 j kg are expected.

Showers will wind down overnight tonight. A mostly dry day is on
tap for Tuesday, although scattered showers are expected over the
easternmost terrain during the afternoon. A potent storm system
will approach the area Tuesday night and Wednesday. This feature
looks to be aimed more directly toward the NW ca coast with similar
to slightly higher rainfall amounts than the latest event. In
addition, more instability is expected to sweep across the coast
and farther into inland areas on Wednesday. The best positive
vorticity advection is expected to precede the greatest
instability by 3 to 6 hours, but this could change. If the dynamic
and thermodynamic forcing are more in sync, thunderstorm coverage
may become more scattered across the area. Shower activity with
this system will linger into Thursday or Thursday night. Modest
responses to rivers are expected this week, with crest levels
remaining below action stage.

A few showers may linger into Friday morning over the extreme n,
with drier weather anticipated for Saturday. Showers are expected
to return on Sunday, but there are indications that the bulk of
the activity may hold off a bit later and be focus more toward the
pacific nw.

Temperatures will remain near normal through the end of the work
week, with temperatures trending upward over the weekend,
particularly over the interior. Sec

Aviation Rain chances will taper off this afternoon, leading to a
more isolated showery regime this evening. MostlyVFR to MVFR
conditions are expected to prevail through the TAF period, but
intermittent drops to ifr conditions are possible with any heavier
showers.

Marine Southerly winds will continue through most of the week,
with gusty winds slower to subside across the inner waters than
previously expected. As a result, have extended the small craft
advisories over the inner waters through early this evening. Winds
will increase again Tuesday night and into Wednesday as another
system approaches the region. Southerly winds around 20 to 25 knots,
with gusts to around 30 knots will be possible over the outer
waters. Steep short-period seas will develop as a result as another
westerly swell moves through the waters on Wednesday. Combined seas
of 9 to 11 feet will be possible across most of the coastal waters
from Wednesday afternoon through early on Thursday. Small craft
advisories for the outer waters have been put in place for the
increasing winds and building seas from Tuesday evening through
Wednesday night. Additionally, winds will remain elevated through
Thursday afternoon, with a switch to northerly forecast by late
Friday night.

Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
